edge of the Tool [GG 1] and the Accessory
Disk [P].
b) Firmly tap the
Wooden Wedge [U] into
position using a hammer. Tap the Wooden
Wedge [U] until the Tool [GG 1] is securely
fastened into the Accessory Disk [P]. Rotate
the Accessory Disk [P] and repeat this
procedure for all six (6) tools.
• Note: Soaking the Wooden Wedges (U) in water
before assembly could increase the gripping power
of the wedges and prolong the time that the tool
stays fixed to the machine.
c) Gently lower the front of the machine until
the tools touch the ground.
d) Pivot the axle so that it is in the
OPERATION POSITION [F] [FIG. 2].
e) Lower the
FRONT SHIELD [A] from its upper
position. Loosen the three (3) CAPSCREWS
[B] and lower the shield so that it is only
3/8-1/2” (10-12 mm) from the ground.

For Light Grinding of Rough Areas. Material is Silicon
Carbide, the “grit” size is designated by number (simi-
lar to most abrasive products). The larger the number,
the finer the grain structure, the smoother the surface
finish achieved, and the longer the grinding stone life.
Some of the available “Grit” Sizes are shown below:
a)
TC-10 Coarse Grit: Maximum material
removal, General grinding & removal
of trowel marks, high spots, and rough
sections of concrete. Life 4-10 hours.
b)
TC-24 Medium Grit: Lower material removal
rate, Finer finish grinding of concrete, and
rough grinding of Terrazzo and other stone
type. Life 6 - 10 hours.
c)
TC-80 Fine Grit: Still lower material removal
rates. For polishing of concrete and medium
grinding on Terrazzo and stone type floors.
Life 8 - 20 hours.
Remove High Spots, Trowel & Rain Marks, Paints,
Sealers & Mastics, Uneven Joints, Aggressive Grinding
of Large Rough Areas, Removal of epoxies, paints
and many thin film coatings, or Final Preparation
for new coating.
Available In Different “Grit” Sizes:
GB-10 General Purpose
GB-20 Abrasive Materials
GB-30 Epoxy & Non-Abrasive Materials
Removal Rates: Up to five (5) times the material
removal rate of Coarse Grinding Stones.
Life: Up to 15 times the life of Grinding Stones.
Comes in a complete kit (P/N 177823) [FIG. 17] that
includes six steel blocks, six tungsten carbide cutters,
hardware and tools, and six wooden wedges.
A replacement cutter kit (P/N 177824) [FIG. 18] is also
available. It includes six tungsten carbide cutters, six
wooden wedges, and all hardware and tools to mount
the cutters.
Removes material with a cutting or shaving action and
works best at removal of thick coatings such as paint
buildups. Not recommended for thin (< 5 mil) films
of materials. Not recommended for adhesives, rubber
deposits and mastics that have a tendency to extrude
or smear rather than “shear” loose from the floor
surface. A water or a water / sand mixture can be
added on the surface to reduce this problem. Adding
additional external weight to the machine can also
improve the material removal rate.
Each tool contains one tungsten carbide insert. Each
insert has eight (8) cutting edges. When one of the
edges becomes dull, loosen the attaching bolt using
the hex wrench provided, and rotate the insert 90
degrees. When these four (4) cutting edges are dull,
simply remove the insert and flip it over to expose
four (4) new cutting edges.
Remove Fiberglass, Ice, Oil-Dry, Foam-Fill Packing
Material & Floor Buildups. Lightly Textures Surface.
Available in three (3) configurations:
a)
Star Wheel: Hardened Carbon Steel
material. For removal of thin coatings
and encrusted accumulations of mate-
rial. Cleaning concrete of asphalt surfaces.
Removing thick build-up of grease, paint,
and some resins. Light scarifying before
application of coatings or sealer. Creates
a swept, or “broomed” type of finish.
b)
Beam Wheel: Medium duty, for concrete
and asphalt scarifying. De-scaling steel
decks. Removing thick material build-up
of grease, paint, and some resins. Twice
the life, near the same cost as a star wheel.
c)
Tungsten Carbide Wheel: Heavy Duty asphalt
or concrete scarifying, or de-scaling of steel
decks. 10 times the life of a star wheel.
Assembly: When new cutters are installed, be sure to
“stagger” the washers in order in avoid any “blind
spots” in the cutter path (On any one cutter block put
the first washer on the opposite end of each stack of
cutters). Also make sure that the wheels can rotate
freely when the attaching Capscrews are tightened.
Bushings: Be sure to inspect the cutter bushings
on a regular basis. Worn bushing can cause the
Scarifier Wheels to break and be thrown against
the inside of the machine frame.
